sensor ฝุ่นละออง ให้ outputเป็น PWM ตามความหนาแน่นของฝุ่นละออง
Specification
The dust sensor module DSM501 is a compact size for a particle density sensor. This
module has a heater to generate heat. Heat creates updraft (upward current of
air) which draw air outside of the module into the module. It is designed to
detect the particle whose size is over one micrometer, which means it can
detect cigarette smoke, house dust, tick, spore, pollen and mildew.
Features:
- PWM output
- Compact Size and Light weight
- Easy installation
- Single power supply
Technical Specifications
- Detectable Particle Size: Approx. 1μm (minimum)
- Detectablerange: 0 ~ 1.4mg/ m³
- Output Singal: PWM (pulse width modulation)
Application
- Air cleaner
- Air conditioner
- Air quality monitor
- Ventilator
